LOS ANGELES, June 13 (Xinhua) -- Dozens of aftershocks have occurred in parts of Southern California following two moderate quakes Saturday night, the U.S. Geological Survey (USGS) said on Sunday.

Some of the aftershocks were felt by residents in areas including San Diego, about 100 miles (160 kilometers) south of Los Angeles, according to the USGS.

The aftershocks, triggered by two moderate quakes measured at 4. 8 and 4.9 magnitude respectively, continued well into Sunday morning, the USGS said.

The 4.8 earthquake followed by a 4.9 quake struck just after 8 p.m. Saturday. The quakes were centered at Borrego Springs, 90 miles (144 kilometers) northeast of San Diego on the U.S.-Mexican border.

Hundreds of people told the USGS that they felt the first two quakes, many of them in San Diego.

The quake also was felt across other parts of Southern California, including the Palm Springs, the northern San Diego County coast, Orange County, San Bernardino and Riverside.

There was no report of injuries or damage.
